PR debug/83941
* dwarf2out.c (struct sym_off_pair): New.
(external_die_map): New global.
(lookup_decl_die): When in LTO create DIEs lazily from the
external_die_map.
(lookup_block_die): New function, create DIEs lazily in LTO.
(equate_block_to_die): New function.
(dwarf2out_die_ref_for_decl): During WPA get the association
from the external DIE map.
(dwarf2out_register_external_die): Record mapping into the
external DIE map.
(maybe_create_die_with_external_ref): New function split out from
DIE generation part of old dwarf2out_register_external_die.

in LTO reference externals directly.
(dwarf2out_abstract_function): When in LTO ignore calls for
decls with external DIEs (already present abstract instances).
(gen_call_site_die): Adjust.
(add_high_low_attributes): Likewise.
(gen_lexical_block_die): Likewise.
(gen_inlined_subroutine_die): Likewie.
